Asymmetric coil spring



FIG. 1 shows a perspective view of an uncompressed asymmetric coil spring showing my new design. The coil spring includes an upper section and a lower section. The upper section has a generally conical shape whereby the diameter of the coil spring in the upper section increases from top to bottom of the upper section. The upper section includes four active convolutions. The lower section is generally cylindrical such that the diameter stays substantially the same along the length of the coil spring in the lower section. The full coil includes nine active convolutions.

FIG. 2 shows a top down view of the asymmetric coil spring shown in FIG. 1; and,

FIG. 3 shows a bottom down view of the asymmetric coil spring shown in FIG. 1. 

CLAIM The ornamental design for an asymmetric coil spring, as shown and described.
